Raptor Prank Kit-  Horn that connects harmlessly to the trailer light plug,  when the owner opens the doors or presses the brake the horn blares.   Extra long / thick Zip tie to wrap around the drive shaft and annoy the owner with a harmless clicking sound at every revolution.   Several hundred feet of caution tape for the owner to stream behing his truck unwillingly as you locate it under the truck and wait for gravity and motion to do the trick.   (Avoid using after parties to avoid unnecessary attention from law enformence.    Becauuse everyone notices several hundred feet of caution tape streaming behind your truck!)
